These weights are accurate to +/- 0.01g based on the Ohaus Scout II (400 x 0.01g ). I have a very cheap "50 x 0.001g" scale but I have found that its actual performance is no better than 0.01g despite the 1mg number. It also "snaps" to 0.000g instead of showing true drift, so you can't measure small weights.
